CHARLES IV. STERICK, OF DE SOTO, MISSOURI, ASSIGNOR OF ONE-HALF TO OFSAME PLACE.

STEAM-COOKER.

SPECIFICATION forming part of Letters Patent No. 464,834, dated December8, 1891.

Application filed August 20,1891.

To aZZ whom, it may concern:

Be it known that I, CHARLES WEsLEY STERICK, a citizen of the UnitedStates, residing at De Soto, in the county of Jefferson and State ofMissouri, have invented certain new and useful Improvements inSteam-Cookers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to an improvement in that class of steam-cookerswherein a base or boiler is used to generate the steam and separatesuperimposed steam vessels or sections connected to said boiler by tubesfor the passage of steam from said boiler to the sec tions, the articlesto be cooked being placed in these latter sections.

The object of the invention is to provide a device of simpleconstruction wherein the maximum amount of space in each superimposedvessel may be used for cooking purposes, and to provide for the passageof the steam from the boiler to each of the said ves sels, as will morefully hereinafter appear. The invention consists in the novelcombination and arrangement of parts, as will be more fully hereindescribed, and particularly pointed out in the claims appended.

The advantages and operation of my device will be understood andappreciated from the following when taken in connection with theaccompanying drawings, in which Figure l is a vertical sectional view ofmy device. Fig. 2 is a vertical sectional view of one section of mycooker. Fig. 3 is a vertical sectional view of a modification of thebase or water section. Fig. 4 is a sectional View of the depending rim.Fig. 5 is a sectional view of a modification of the rim. Fig. 6 is adiagram of a blank, showing the manner in which the bottom and dependingflanges of the vessels may be made of a single piece of metal; and Fig.7 is a section of abottom and depending flange of this latterconstruction.

Similar letters of reference indicate corresponding parts throughout theseveral views.

In the drawings, a designates the base or water section, and b o d thesuperimposed steam-sections. The water-section is provided with an inlete and the spout ft whereby it may be readily filled with water whendethe lower edge of the side of the section out- Serial No. 403,235. (Nomodel.)

sired without removing the superimposed cooking receptacles. Thiswater-section is also provided with a series of circular openingsthrough its bottom, each opening being covered by a hollow sheet-metalcone Z, projecting into said section and secured to the bottom aroundthe edge of the opening, thereby greatly increasing the amount ofsurface exposed to the action of the heat, and, as is manifest,producing steam much more quickly than could be done with a smoothbottom. The sections are fitted into each other by means of a rim ordepending flange g at the lower edge of each section, said rim or flangebeing slightly smaller in diameter to fit the internal diameter of thesections. The rims g serve as bases or supports for the cooking-sectionswhen they are separated, and they are each formed of the vertical outerwall 7L, the inwardly and upwardly inclined wall '5, extending from thelower edge of the vertical wall h, and the horizontal flange s, I formedintegrally with and extending outwardly from the upper edge of the innerwall 2', as shown most clearly in Fig. 4. One of these supporting rimsor flanges g is secured to the lower end of each of the sections,together with the bottom of same, by bending 8o wardly, as shown at It,then turning under the bent-out end, as at is, forming the radial flangeZ. The outer edge of the bottom and the outwardly-extending flangej ofthe rim 9 are clamped between the upper and lower portions of the saidflange Z, making a very strong and durable joint. The horizontal flanges is forced against the bottom of the section and the upper end of thevertical wall of the rim, strongly bracing the rim and bottom andpreventing the rim being dented or forced out of shape under ordinaryconditions, thereby insuring a tight fit between the sections. Thesections are prevented from telescoping or sliding too far into eachother by the flanges Z, which rest up )n the upper edges of thesections, as shown.

To theinner sides of the cooking-receptacles or steam-seotionslsecurecurved plates, which project slightly below the bottoms of saidsections and are secured at their longitudinal edges to the sides of thesections, forming with said section semi-cylindrical tubes. In the lowersection b are three of these curved plates on m m contained one withinthe other, the outer one m terminating a short 5 distance below theupper ends of the inner ones on m, for a purpose that will presentlyappear. In the section are two similarlycurved plates m m, contained onewithin the other, whose lower ends fit over the upper to ends of theplates m m of section Z) below, the outer plate m of section 0terminating slightly below the upper end of plate m of the same section.In the section d I secure the plate m, whose lower end fits the upper Iend of plate m of section 0 below, forming with said plate and plate mof section b a continuous tube for the passage of steam from thewater-section to section d. Thetubesm m form a continuous tube for thepassage of steam from the water-section to the section 0. In like mannersteam from the water-section is admitted to section I) through tube mEach section is provided with handles 19 p, and the upper section cl isprovided with a cover g. This cover q will fit any of the receptacles,and, as is manifest, any number of the sections may be used and thecover placed on the uppermost one.

In Fig. 3 of the drawings I have shown a modification ot' theboiler-section, said modification having a series of dependingcorrugations t in its bottom for a similar purpose as the upwardlyextending hollow cones shown in Fig. 1. This is to give greater heat- 35 ing-snrface to the bottom.

In Fig. 6 of the drawings is shown a diagram of a blank from which thebottom of the cooking-vessel and rim 9 may be stamped in a single piece.In this construction the depend- 0 ing rim is formed by bending underthe part of the blank between the dottedlines 1 and 2,then bending downthe part between lines 2 and 3 to form the Vertical wall of the rim. Thehorizontal flange s is then formed by bending inwardly at right anglesto the main body of the metal the part of the blank between the dottedlines eand 5, and the rim is completed by bending upwardly and inwardlythe part between the dotted lines 3 and 4 to form the inclined wallt' ofthe rim. This construction makes a very' strong and durable rim. Iffound necessary, V-shaped recesses may be formed in the outer edge ofthe blank at diametrically-opposite points, as shown by dotted lines inFig. 6, to permit of the turning under of the outer edge of the blank.

In Fig. 5 I have shown the rim 9 formed of two pieces, the lower end ofthe vertical wall being turned inwardly and upwardly over the lower edgeof the inclined wall and soldered,

as shown. This construction may be preferred in some instances to theones described in the foregoing.

Having thus fully described my invention, what I claim is- 1. Asteam-cooker consisting of a boiler, a series of superimposedcooking-vessels, a series of sectional semi-cylindrical tubes containedone within the other, said tubes being secured to the sides of thecooking-vessels and connecting said vessels to the boiler, and means forfilling the boiler when desired, substantially as and for the purposeset forth.

2. A steam-cooker consisting of a boiler, a series of superimposedcooking-vessels, a series of sectional semi-cylindrical tubes containedone within the other and secured to the sides of the receptacles,thereby connecting the receptacles to the boiler, a series of hollowcones or projections in the bottom of the boiler, and a spout andopening in the side. of the boiler for filling said boiler with waterwhen desired, for the purposes set forth.

3. A steam-cooker consisting of a boiler, a series of superimposedcooking-vessel's, a series of semi-cylindrical tubes contained onewithin the other and secured to the side of the cooking-vessels,connecting each receptacle to the boiler, and an annular depending rimsecured to the bottom of each receptacle for fitting the sectionstogether, said rim consisting of a radial flange j, adownwardly-extending vertical side h, an upwardly and inwardly inclinedportion 1', and the outwardlyextending horizontal portion 8,substantially as and for the purposes set forth.

4. A circular vessel provided with a bottom, said bottom being securedto the vessel by clamping the lower end of the latter over upon itsedges, and a depending'flange 9, consisting of the outer wall h andinner inclined wall 2', having outwardlyprojecting flanges, the outerflange being clamped between the bottom and flanged end of the vessel,substantially as described.

5. The combination of the boiler-section a, the superimposedsteam-section b c d, fitted one within the other and provided withbottoms, the open-ended semi-cylindrical tubes m m m secured to theinterior of the section I), one within the other and all communicatingwith the boiler, the outer one terminating below the bottom of thesection next above, open-ended semi-cylindrical tubes m m, secured onewithin the other on the interior of the section 0, the lower ends ofboth these tubes extending through the bottom of the section andembracing the upper ends of the lower tubes m m, and an open-ended tubem, secured on the interior of the uppermost section cl and communicatingwith the tube m of the section below, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
